Say What? “soda” means “headache remedy”. Its element symbol comes from the Latin word, natrium, which stands sodium carbonate What is sodium?
-Sodium was first isolated by Sir Humphry Davy in England
-Sodium is never uncombined in nature-Sodium has the atomic number of 11 and the mass of 22.9898 g/mol
-Sodium is in the group, 1A, which is all of the alkali metals
-Sodium is really common. It is the 6th most abundant element on earth
-It is silvery white and is a highly reactive element
-There are 18 isotopes of sodium, and all of them are radioactive
-Melting point: 370.95 K (208.04°F) -Boiling point: 1156 K (1621°F) -Sodium is mostly found as sodium chloride (table salt), and sometimes found as sodium carbonate and sodium sulfate -Sodium is solid at room temperature
Cost?
-Metallic sodium is 15-20 cents/lb. It is the cheapest of all elements
What are its uses?
-Sodium vapor is in streetlights and produces the yellow light
-table salt (NaCl)
-baking soda (NaHCO3) -Chile saltpeter (NaNO3)
